AGRICULTURAL IMPLENIAENT.

SPECIFICATION forming part of Letters Patent No. 721,582, dated February24, 1903. Application filed July 28, 1902. Serial No. 117,307. A(lilomodel.)

To all whom it may concern,.-

Beit known that I, DAVID LUB1N,a citizen of the United States,andaresident of the city of New York, borough, of:v Manhattan, in thecountyand State of New York, have invented a new and ImprovedAgriculturalImplemen t, of which the following is a full, clear, andexact description. Y

This invention relates to improvements in agricultural implementsoperated by a motor carried on a vehicle; and the object is to provide adevice of this character with them echanism so arranged that the motorwill alternately move the vehicle and operate the ground digging andpulverizing tools.

I Will describe an agricultural implement embodying my invention andthen ,point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forminga part ofthis specification, in which similar characters of reference in di-lcate corresponding parts in both the figures.

Figure 1 is a side elevation of an .agricultural implement embodying myinvention, and Fig. 2 is a plan View thereof.

The vehicle comprises a body or platform 1, mounted on the rear wheels 2and the front wheels 3. The front wheels are designed to be employedalso as steeringwheels, and

therefore I have shown a sprocket-chain 4A extended from asprocket-wheel on the front axle to a sprocket-pinion 5,'attached to thelower end of a steering-rod 6. l

Mounted on the vehicle'is amotor, here shown as consisting of a;boiler?, supplying steam to the cylinders 8, thepistons in thesecylinders having theirstems 9 connected with the cranks 10 of adriving-shaft 1l. On this driving-shaft 11 is a bevel-gear 12,which ismovable lengthwise oftheV shaft, butV is so connected thereto as torotate with the shaft. The bevel-gear 12 meshes with a bevel-gear 13 ona worm-shaft 14, the worm 15 of which engages with a worm-wheel 16 on acounter'- shaft 17.b i

Carried on the vehicle are digging-tools, here shown as forks 18,movable in a rockshaft 19, having its bearings in the side por` tions ofthe platform 1. These digging tools or tines are designed to be forcedinto the ground vertically one after another, so that a motor ofcomparatively low horse-power may operate them.

Extended upward from each digging-tool is an arm 20, designed to beengaged with a push-lever 21. Extended upward from each push-lever is apush-bar 22, having a notch in its upper end in which a cam or crank 23is designed to engage. As here shown, there are three digging f tools,and consequently three levers and three cranks, for engagingconsecutively with the three push-rods.` After forcing the digging-toolinto the ground and when the push-rod 22 shall have been released by itscam or crank a spring 24 will move the lever to its uppermost or normalposition, and the forward movement of the push-rod will be limited by astop 25.

Arranged rearward of the digging-tools is a pulverizing orbreaking'device,consisting of fingers 26, extended from a shaft 27, andrearward of this rotary breaking device are levcling-lingers 28. Theseleveling-lingers are connected to a crossbar 29 and extended slightlyforward, then curved rearward, and then down ward,so that their extremeends will engage lightly on the soil and level or rake it. The forwardportions of these devices 28 are in the line of movement of thedigging-toolsthat is, when the digging-tools move upward they will passbetween the devices 28 and pulverize any dirt that may be carriedthereby. Preferably these devices 2 8 are spirally twisted.

On the counter-shaft 17 isa mutilated gear 30, the teeth of which at acertain time are designed to engage with a pinion 31 on a driving-shaft32. On the outer end of this shaft 32 is a sprocket-pinion 33, fromwhich a chain 34 extends to a connection with a sprocketwheel 35 on therear axle. The teeth of this mutilated gear 30 are designated at acertain time to engage with a pinion 36 on a shaft 37, carrying a cam 38on one end, the said cam being in the form of a slot-cam, and in theslot the wrist-pin 39 of a draw-bar 40 engages. This draw-bar at itsrear end connects with a crank-arm 41 on the rock-shaft 19. 30 aredesigned to engage with a pinion 41 on a shaft 42, and on this shaft 42is a sprocketpinion 43, from which a chain 44 extends to At another timethe teeth of said gear a connection with a sprocket-pinion 45 on theshaft 46, -to which the cams 23 are connected. Also connected to theshaft 17 is a mutilated gear 47, designed to engage with a pinion 48, onthe shaft of which a series of gear-wheels 49 is mounted. Thesegear-wheels 49 conneet with rack portions formed on draw-rods 50, therear ends of which are connected to the digging-tools. On one end of theshaft 37 is a sprocket-wheel 5l, and this sprocket- Wheel 5l isconnected by a chain 52 with a sprocket-pinion 53 on the shaft 27.

Loosely mounted on the shaft 11 is a sprocket-pinion 54, having a clutchmember on one side designed to be engaged by a clutch member carried bythe gear 12, and this pinion 54 has a chain connection 55 with asprocket-pinion 5G, attached to the shaft 32. This mechanism is fordriving the vehicle forward or from field to field when it is notdesired to operate it in cultivating the ground.

In the operation when the vehicle is at a standstill the teeth of thegear 30 will first engage with the gear-wheel 41, which will cause arotary movement of the cams 23 to force the digging-tools into theground one after the other, as before mentioned. The teeth of the gear30 after leaving the wheel 4l will engage withthe gear S6, which byoperating the cam 38 will cause the diggingtools to swing upward with aload of earth, and at this same time the rotary breaking devices 26 willbe set in rapid rotation, so as to finely pulverize the earth liftedbetween them by the diggingtools. After moving out of engagement withthe gear 36 the teeth of the gear 47 will engage with the small pinion48, causing a rapid rotation of the shaft carrying the gear-wheels 49,and these gear-wheels meshing with the racks of the draw-rods 50 willdraw the digging-tools back to their normal position or with the ends oftheir tines close to the lower side of the rock-shaft 19, so that thecam 38 on its reverse motion will move the digging-tools to verticalposition to be again operated. The teeth of the gear 80 will now engagewith the pinion 3l and cause the vehicle to move forward a sufficientdistance for the next operation of the digging-tools, and the operationof course will continue in this alternate fashion from one side of afield to the other.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. An agricultural implement comprising a vehicle, amotor mounted on the vehicle, digging-tools carried on the vehicle, arotary breaking device carried on the vehicle, and means operated by themotor for alternately operatin g the digging-tools and rotary breakerand moving the vehicle forward, substantially as specified.

2. An agricultural implement comprising a vehicle, a motor mountedthereon, a diggingtool mounted to swing on the vehicle, means forforcing the tool downward into the ground, a rotary breaking devicerearward of the digging-tool, and means operated by the motor foralternately moving the vehicle forward and then operating thedigging-tool and breaking devices, substantially as specified.

3. An agricultural implement comprising a vehicle, a motor mountedthereon, a series of digging-tools mounted on the vehicle, the saidtools having vertical movement and an upward-swinging movement, meansoperated by the motor for causing said movements, a

rotary breaker rearward of the digging-tools, and means operated by themotor for rotating said breaking-tools,substantially as specilied.`

4. An agricultural implement comprising a vehicle, a motor mountedthereon, a driving connection between the motor and vehicle,digging-tools carried on thevehicle, means operated by the motor foractuating said digging-tools, a rotary shaft operated from the motor,breaking tines or fingers extended outward from said shaft, andraking-tines carried by the vehicle rearward of the rotarybreaking-tines, substantially as specified.

5. An agricultural implement comprising a vehicle, a motor mountedthereon, a driving connection between the motor and vehicle,digging-tools carried on the vehicle, means operated by the motor foractuating said digging-tools, a rotary shaft operated from the motor,breaking tines or fingers extended outward from said shaft, andraking-tines carried by the vehicle rearward of the rotary breakingdevice, the said raking-tines being extended forward, then curvedrearward and downward and spirally twisted, substantially as specified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
